Stream lined your equipment as well as yourself while diving ie make sure your equip isn't hanging and hold your hands, fingers interlaced at your waist
viscous drag- the same as swimming or diving into a pool.
Scuba health insurance is the insurance that protects you while you are scuba diving if you need any health procedures because of your diving. For example, if you were to get the bends from scuba diving, or if your lung were to rupture from holding your breath, this scuba insurance would cover it. Since paying for these procedures are very expensive "out of pocket," this means that you might not get the treatment unless you have this, or at least you could not pay it off.

Scuba divers require increased air pressures in their air tanks while diving because the pressure on their bodies increases.
Yes, scuba diving can definetly benefit your health through physical fitness, cardiovascular health, respiratory health, stress relief, mental well-being, increased flexibility, and of course social interaction.
It is, until terminal velocity is reached. That is when the air resistance is equal to the force of gravity, thus you don't accelerate any more.
It is diving on a high diving board.
The percentage of oxygen in diving varies depending on the diving depth and the type of diving. For recreational diving, the typical oxygen concentration is around 21%. However, for technical diving, the oxygen concentration can be increased up to 100% to reduce the risk of nitrogen narcosis at greater depths. Helium is often used as a diluent gas in technical diving to reduce the amount of nitrogen in breathing mixtures at very deep depths. The percentage of helium varies typically between 0% and 90% depending on the dive plan and depth.
Fins provide much greater force in water than your bare foot, due to the increased surface area. This increased force is necessary because the additional equipment needed for scuba diving (tank, buoyancy compensator, regulators, etc...) increases the amount of drag and weight of your body in the water. Without fins, you would use a great deal of energy and not get very far.
In my diving club, there are no members in the US diving at the moment.
Competitive diving is when an athlete participates in competitions in the area of springboard diving. There is spring board diving, which is done on either a one meter or a three meter diving board. Then, there is platform diving, which is most commonly done on a five meter, seven meter and ten meter. Diving is a competitive sport practiced in the Olympics, where they do both springboard and platform diving.
Professional Diving is a type of diving where the divers are paid for their work. Recreational diving or sport diving is a type of diving that uses SCUBA equipment for the purpose of leisure and enjoyment. Military, navy, rescue and police diving courses need to be taken per your division or location. Technical and scientific diving is mainly for research and exploration.
